  • Silicone durability – once cured, silicone exhibits excellent long-term resistance to natural weathering, including: extreme temperatures, ultraviolet radiation, rain and snow, with negligible change in elasticity.
  • Movement capability – once cured, silicone exhibits +/- 50% movement in both extension and compression, capable of withstanding daily exposure to various weather conditions.
  • Adhesion – RGS7700 features primerless adhesion to most nonporous construction materials, eliminating the risks associated with improper primer application on those materials and reducing costs associated with primer and subsequent labor. SWS can be used with many substrates and finishes, including: glass, polycarbonate, vinyl, plastics, aluminum, and treated and untreated wood. RGS7700 forms a strong bond capable of withstanding harsh conditions.


  • Adjustable work life – mix ratio of base and catalyst can be adjusted to suit the project or climate, as the cure speed can be increased or decreased, allowing flexibility in application.
  • Accelerated cure – RGS7700 cures quickly, building adhesion rapidly and accelerating production time.


  • Color assortment – available in four standard colors and translucent.

Limitations: Customers must evaluate the product and make their own determination as to fitness of use in their particular applications. See the applicable product data sheets for additional product information.
